The reaction of rhenium (VII) trioxo complexes containing the ligand sets scorpionate, [HB(pz)₃]ReO₃ (6), [Ph-B(pz)₃]ReO₃ (7), and [{HC(pz)₃}ReO₃][ReO₄] (8) and pyridine/pyridine-type ligands [(4,7-diphenyl-1,10-phen)(Br)ReO₃] (12), [(4,4'-di-tert-butyl-2,2'-dipyridyl)(Cl)ReO₃] (13), and [(py)₂Re(Cl)O₃] (4), with diphenyl ketene, has led tothe isolation of six novel [3 + 2] cycloaddition products. These air-stable solids 9-11 and 15-17 are the result of[3 + 2] addition of the O=Re=O motif across the ketene C=C double bond. Five of the six [3 + 2] cycloadditionproducts have been structurally characterized by single-crystal X-ray diffraction and in all cases by ¹³C NMR andIR spectroscopies.
